A combined micro-PET/CT scanner for small animal imaging

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006
A micro-PET/CT system was developed by combination of an in-house micro-CT and a microPET® R4 scanner. The cone-beam micro-CT consists of a rotational gantry that fits an X-ray tube, a CCD-based X-ray detector, and motor-driven linear stages. The gantry was designed to be coaxial with the scanner of microPET® R4.

PET-based geometrical calibration of a pinhole SPECT add-on for an animal PET scanner

Physics in Medicine and Biology, 2013
We developed SPECT imaging capability on an animal PET scanner to provide a cost effective option for animal SPECT imaging. The SPECT add-on sub-system was enabled by mechanically integrating a multiple-pinhole collimator in the PET detector ring. This study introduces a method to calibrate the geometrical parameters of the SPECT add-on using the PET ...

FIRST RESULTS WITH THE CLEARPET SMALL ANIMAL PET SCANNERS

2006
The Crystal Clear Collaboration has designed and built a family of high resolution small animal PET scanners. These were designed to be used in research laboratories and provide maximum modularity and flexibility. The source code of the data acquisition and reconstruction software is freely available to the users.

Design Considerations for Small Animal PET Scanners

2014
Positron emission tomography (PET) is an established imaging technique currently used for the clinical management of disease in oncology, cardiology and neurology [1–3]. PET is nowadays integrated in the clinical routine and is acknowledged as a sensitive clinical molecular imaging method.

YAP-(S)PET small animal scanner: Quantitative results

IEEE Transactions on Nuclear Science, 2003
At present, at the Dept of Experimental and Clinical Medicine of the University of Ferrara, the YAP-(S)PET scanner is employed in small animal SPECT studies, with 99mTc labelled radiotracers, dedicated to obtain quantitative activity measurements in a region of interest (ROI) directly from a reconstructed image of a rat, with respect to the traditional

Raytest ClearPET™, a new generation small animal PET scanner

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
The ClearPET is a high-performance small animal PET scanner that has been developed by the Crystal Clear Collaboration (CCC) and is now commercially available to customers worldwide through the Raytest group. Its high sensitivity and spatial resolution are achieved, thanks to a patented phoswich configuration made of two types of scintillating crystals:

Evaluation of the first Silicon Photomultiplier matrices for a small animal PET scanner

2008 IEEE Nuclear Science Symposium Conference Record, 2008
A high resolution small animal PET scanner that employs Silicon Photomultiplier (SiPM) matrices as photodetectors is under development at the University of Pisa. The first SiPM matrices fabricated by the Center for Scientific and Technological Research, FBK-irst, Trento, Italy, are being evaluated for this purpose.

System electronics for the MiCES small animal PET scanner

2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2003
The final electronics system for the microcrystal element scanner (MiCES) small animal positron emission tomograph is described. Groups of four position-sensitive photomultiplier tubes (FSPMTs) are connected to an adapter board which provides four output signals from each PSPMT.

"ANIPET" a versatile PET scanner for imaging small animals

1998 IEEE Nuclear Science Symposium Conference Record. 1998 IEEE Nuclear Science Symposium and Medical Imaging Conference (Cat. No.98CH36255), 2002
The authors are presently constructing "ANIPET", a new high spatial resolution PET scanner for imaging small animals. This instrument will be used to investigate new tracers and as a substitute for autoradiography. The instrument uses two pixellated BGO crystal arrays coupled to position-sensitive PMTs. Animals can be imaged in two modes.

An MR compatible PET scanner for imaging small animals

Nuclear Medicine Communications, 2004
Combined PET-CT scanners are becoming standard for clinical PET imaging. The development of a combined PET-MR scanner poses greater technological challenges. A prototype small animal MR compatible PET scanner has previously been designed, constructed and evaluated in collaboration with UCLA School of Medicine.
